To help mitigate climate change, it is essential to consider the importance of façade glazing in promoting energy efficiency and thermal comfort. This article carries out a qualitative analysis of two projects, starting with the identification of the envelopes as a starting point, followed by the choice of glass typologies and, finally, a comparative analysis focusing on the reduction of solar exposure in internal spaces. The first project analyzed is the Jack H. Miller Center - USA, which received LEED certification, while the second, the Unibra University Center - BR, required interventions after its completion. The studies show that the application of thermochromic films can help improve thermal comfort.

In response to the global climate crisis, urgent measures are required to reduce greenhouse gas emissions in alignment with the goals of the Paris Agreement. As energy consumption accounts for 36% of total emissions, and buildings contribute significantly to both direct and indirect emissions, it is crucial to enhance the energy efficiency and self-sufficiency of buildings. This article conducts a case study to evaluate the formal structure, spatial layout, and sustainable strategies employed in residential units within the Pedra Branca neighborhood (Santa Catarina, Brazil), using the methodology developed by Brandão and Schneider. The findings indicate that the housing units predominantly consist of three bedrooms, along with two to four bathrooms. The analysis revealed partial integration between the kitchen and service areas, with full integration being less common. Corridor layouts were found to make the greatest contribution to sustainability and internal space quality. Although some configurations did not directly support cross-ventilation, there was a clear focus on environmental comfort and the use of passive design strategies. This study highlights the potential of such configurations to improve energy performance and contribute to the development of climate-positive neighborhoods.

To contribute to the control of climate change, it is essential to consider the relevance of facade glazing for promoting energy efficiency and thermal comfort. This article qualitatively analyzes two projects, starting with the identification of the envelopes as the initial parameter, followed by the selection of glass typologies, and finally, by the comparative analysis, considering the reduction of solar exposure inside the environment. The first project was the Jack H. Miller Center — USA, which obtained LEED certification, while the second, the Unibra University Center — BR, required intervention after its execution. The studies demonstrate that it is possible to improve thermal comfort by applying thermochromic films.

In the face of the global climate crisis, it is urgent to carry out actions that collaborate with the reduction of greenhouse gas emissions, in order to achieve the goals set out in the Paris Agreement. In this sense, it was necessary to analyze buildings in sustainable climate-positive neighborhoods, since energy consumption contributes to 36% of total emissions, and buildings represent a significant portion of direct and indirect emissions [23, 24], so it is intended to stimulate energy efficiency and self-sufficiency of these. This article uses the case study to analyze the formal structure, spatial distribution and sustainable strategies of the housing units in the Pedra Branca-SC-BR neighborhood, based on the methodology of Brandão and Schneider. From the study, to identify the existing floor plan patterns, it was found that the units are mostly composed of three bedrooms, two and four bathrooms and toilets, as well as there is partial integration between the kitchen and service areas, the integral option is a minority. From the analysis, it is understood that corridor plants are the ones that best contribute to the sustainability and quality of the internal space. It was found that although the other configurations did not contribute directly to cross ventilation, there was a concern with environmental comfort and passive strategies.

The aim of our study was to apply a biomimetic approach, inspired by the Ammophila arenaria. This organism possesses a reversible leaf opening and closing mechanism that responds to water and salt stress (hydronastic movement). We adopted a problem-based biomimetic methodology in three stages: (i) two observation studies; (ii) how to abstract and develop a parametric model to simulate the leaf movement; and (iii) experiments with bimetal, a smart material that curls up when heated. We added creases to the bimetal active layer in analogy to the position of bulliform cells. These cells determine the leaf-closing pattern. The experiments demonstrated that creases influence and can change the direction of the bimetal natural movement. Thus, it is possible to replicate the Ammophila arenaria leaf-rolling mechanism in response to temperature variation and solar radiation in the bimetal. In future works, we will be able to propose responsive facade solutions based on these results.
